Mission of DeRisk

Cost reduction within offshore wind energy is central for achieving the 2020 goal of 50% wind share of the Danish electricity supply. DeRisk provides a key contribution by providing new design methods with reduced risk and uncertainty for extreme wave loads (ULS, Ultimate Limit State) which are often design-giving for the support structure.

The structural response for wind turbine structures of mono-pod and jacket type are examined through aero-elastic calculations and analysis of lab and field data. For the first time, new methods for numerical uncertainty quantification are applied to quantify the model sensitivity. The new tools and detailed investigations are sythesized into a de-risked design procedure for ULS wave loads.
